Twin sisters Bibike and Ariyike are enjoying a relatively comfortable life in Lagos in 1996. Then their mother loses her job due to political strife and their father gambles away their home, and the siblings are thrust into the reluctant care of their traditional Yoruba grandmother. Inseparable while they had their parents to care for them, the twins' paths diverge once the household shatters: one embracing modernity as the years pass, the other consumed by religion. This debut novel follows the fate of one family over the course of two decades in Nigeria. Written with astonishing intimacy and wry attention to the fickleness of fate, Black Sunday delves into the chaotic heart of family life. In the process, it tells a tale of grace in the midst of daily oppression, and of how two women carve their own distinct paths of resistance.
